A look at potential cutbacks at national parks

's 398 national parks if forced federal budget cuts are enacted next week. The plans include:

— Cape Cod National Seashore, Mass.: Closure of the Province Lands Visitor Center; reduction of seasonal natural resource personnel would force the closing of Great Beach to protect nesting shorebirds.

— Yosemite National Park, Calif.: Staff reductions that would end guided ranger programs at Wawona and the Mariposa Grove of Giant Sequoias; elimination of a program in which 3,500 volunteers provide 40,000 hours of activities; less frequent trash pickup due to loss of campground staff.

— Sleeping Bear Dunes National Lakeshore, Mich.: Invasive species would go untreated. Also, reductions in seasonal hiring would reduce protections for endangered piping plovers. Plover chicks and adults would be more susceptible to death from human activities and predation.
